官员排名赛与环境政策执行——基于环境约束性指标绩效的实证研究

以从2006年开始实行的环境约束性指标为研究对象,结合晋升锦标赛和弱排名激励理论,提出了官员排名赛理论,认为约束性指标制度的建立为地方政府提供了环境绩效排名的平台,由此推动了地方政府环境政策执行力度。利用2006—2015年中国省际环境数据,采用动态面板数据估计方法,实证检验了各省环境绩效排名对其未来环境政策执行力度的影响。实证结果表明,环境绩效排名落后的省份在未来1~3年显著提高了节能和减排的政策执行力度。     

基于组织协同系统的创客组织发展稳定性实证分析

创客组织是实现组织协同创新的重要载体。创客位于组织协同系统的核心层，创客入驻创客组织的创新状态决定了协同创新发展状态；创客组织位于组织协同系统的中间层，起组织协调作用，其发展稳定性影响着整个系统；协同组织位于外部层，其参与程度决定了整个系统的组织协同和协同创新吸引能力。基于波动系数计量模型，对240家创客组织的12项评价指标进行分析，结果显示，以高校主导的创客组织衡量指标波动系数为标准，创客组织在整体上处于发展不稳定状态；分类别分析结果表明，高校和科研院所主导的创客组织发展稳定性明显优于企业和个人主导的创客组织。研究结果可以为完善创新政策、促进创客组织稳健发展提供参考。     

Driving force from authorities: the evolution of innovation system for biomedical industry in China

Over the past 30 years, China has fully exploited its advantage to steadily foster an innovation system for the biomedical industry with Chinese characteristics, that is, ‘Government-guided, resource-integrated and long-term planning.’ The system originated from historically famous ‘863 program’ in the 1980s, evolved with a series of favourable policies in the different periods, and eventually has taken shape in the industrial clusters across the country. It features with a systematic and integrated R&D infrastructure (or public platform) at different levels. In this study, China’s biomedical innovation system will be examined and the leading role of Chinese authorities will be explored from the perspective of Triple Helix theory. As the ‘highland of innovation’, Shanghai case is highlighted with plentiful information gathered from primary sources in the involved agencies for the first time, including the Shanghai Biopharma Service Platform.     

Bidder's Gain: Evidence from Termination Returns

In most cases, bidder's stock returns around merger announcement convey more information than the synergy created from the acquisition. To overcome the interpretation problem, I study the bidder's return from the perspective of deal termination. Using a hand‐collected dataset on terminated merger proposals, I investigate termination returns in deals canceled for reasons unrelated to the bidder's stand‐alone valuation. I find that bidder's gain varies significantly with the type of target acquired. Further evidence suggests that the liquidity need of private target significantly contributes to the positive gain to the bidder.

Opening the Black Box of Upper Echelons in China: TMT Attributes and Strategic Flexibility

Many scholars have suggested that strategic flexibility is a critical firm capability to survive in today's competitive arena. The decision to take strategic actions to make the firm more strategically flexible typically originates in the top management team (TMT). As the principal decision‐making unit of the firm, TMT members' information acquisition and processing capabilities and subsequent interpretation of environmental changes critically influence the decision to make the firm more strategically flexible to achieve a better fit with its market environment. Therefore, in order to understand how firms can adapt to environmental changes, scholars must study the sociopsychological processes of interaction among members of the TMT. This study examines the relationships between TMT's sociopsychological attributes (shared vision, social integration, and political ties) and strategic flexibility, which is decomposed into organizational flexibility and technological flexibility. The study further investigates how the level of competitive intensity can moderate the relationships. All the hypotheses are tested using structural equation models based on the survey data from 227 firms in China. The results show that organizational flexibility mediates the impact of TMT's social integration and political ties on technological flexibility. Surprisingly, a TMT's shared vision for the firm neither impedes nor facilitates the firm's effort in attaining the desired degree of organizational flexibility. However, TMT's shared vision does have a positive and direct impact on technological flexibility. Moreover, intense competition amplifies the positive impact of TMT social integration on the degree of organizational flexibility, but there is no significant moderating effect of competitive intensity on the relationship between a TMT's political ties and organizational flexibility. The results extend previous research by highlighting the importance of TMTs' sociopsychological attributes in driving technological flexibility, through the mediating impact of organizational flexibility.     

Opportunity recognition and SME performance: the mediating effect of business model innovation

Opportunity recognition is vital for small and medium-sized enterprises (SMEs), but SMEs face challenges in capturing recognized opportunities. Given that opportunity recognition does not automatically lead to higher SME performance and that SMEs need to take appropriate actions to exploit recognized opportunities to achieve better performance, it is imperative to explore the mediators that enable SMEs to translate opportunity recognition into higher performance. This study proposes that business model innovation may be a key conduit through which opportunity recognition affects SME performance. Based on a dataset of 155 SMEs, we find that the positive relationship between opportunity recognition and SME performance is mediated by business model innovation. These findings not only aid SMEs in accomplishing the performance effect of opportunity recognition, but also provide some insights into the implications of business model innovation.

The Chinese Stock Dividend Puzzle

In this paper, we examine the announcement effects of dividends with an emphasis on stock dividends in China's capital market. We find that dividend-paying stocks exhibit significantly positive abnormal returns while non-dividend-paying stocks show a negative announcement effect. Further, we document that the cumulative abnormal returns for pure stock dividends and combined dividends are the main drivers of this announcement effect. In contrast, pure cash dividend stocks experience no significant price run-up before announcement. The significant announcement effect of stock dividends is robust to controlling the earnings surprise effect. We offer some discussion of the possible explanations.
